Overview

Panthera e73 is an open-source printed circuit board by passinglink, from the passinglink/pcb repository on GitHub, published under the MIT licence. It is a 2-layer board of 113.5 × 35 mm with 22 parts on 62 nets, routed with 293 tracks and 52 vias.

It is built around the E73-2G4M08S1C, MIC5219-3.3YM5 and PESD5V0L1BA,115-ES, with the PESD12VL1BA,115-ES among its other parts. Its parts include 11 connectors, 4 resistors, 3 diodes, 2 ICs and 1 capacitor.

Notes

R1 is unnecessary, unless you want to probe the touchpad's interrupt pin with a logic analyzer
R2 and R3 are needed only if you're using the USB-C connector
D1-3 are unnecessary, but recommended to protect from static discharge

Questions

How big is the Panthera e73 PCB?

It measures 113.5 × 35 mm and has 2 copper layers, 0.8 mm thick.

What parts does the Panthera e73 use?

22 parts, built around the E73-2G4M08S1C, MIC5219-3.3YM5, PESD5V0L1BA,115-ES and PESD12VL1BA,115-ES. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Panthera e73 KiCad files?

From the passinglink/pcb repository on GitHub, at the commit this page was made from: the board is legacy/panthera_e73/panthera_e73.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Panthera e73 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
